Eastern Screech-Owl

Megascops asio

This robin-sized nightbird is common over much of the east, including in city parks and shady suburbs, where many human residents are unaware they have an owl for a neighbor. The owl spends the day roosting in holes or in dense cover, becoming active at dusk. Despite the name, screech-owls do not screech; the voice of this species features whinnies and soft trills.

Conservation status

Still widespread and fairly common, but thought to have been gradually declining in various parts of range. Helped in some areas by provision of nest boxes.

Woodlands, farm groves, shade trees. Generally favors deciduous or mixed woods, but may be found in any habitat having some open ground and some large trees, from forest to isolated groves to suburban yards. May be absent from some areas because of lack of dead snags with suitable nesting holes.

Feeding Behavior

Forages at dusk and at night. Hunts mostly by watching from a perch and then swooping down to take prey from the ground or from foliage. Also catches flying insects in the air. Can locate prey by sound as well as by sight.

Eggs

4-5, sometimes 2-8. White. Incubation is mostly by female, averages about 26 days. Male brings food to female during incubation. Young: Both parents bring food for young. Adults may bring back small, wormlike Blind Snakes and release them in nest, where the snakes burrow in debris in bottom of cavity, feeding on insects there, perhaps helping protect the young from parasites. Young leave the nest about 4 weeks after hatching, are fed by parents for some time thereafter.
